I wrote this driver because I needed it.It Works!!! make sure you have your display set to 640x480 to start with.If the Screen is a mess after you change to 800x600 you will need a monitor that supports 60Hz 800x600.Once in 800x600 change the Adaptor Refresh Rate to 56Hz.Turn your computer off,reconnect the Philips Monitor and restart your Computer.Everything should be O.K.
